WALL

Application led July 3,

T0 all whom it may concern:

Be it known that we, ROY M. Moss and OSCAR B. PULis, citizens of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and vuseful Improvements in lVall Forms, of which the following is Va specification.

This invention has to do with what are known commonly as metal wall forms, and involves construction features useful preferably for straight all form units, though certain essential features are equally adapted for use -on circular wall -or mold forms of the metaltype.

It is customary to `hold metal wall forms in position, properlyspaced apart, by -means of tie wires which are embedded in the concrete wallgbuilt by the use of the forms. An object of our invention has been to do away with the need of employing the. tie wires, the `use of which involves a .rather expensive operation of twisting` or adjusting Vin connection with the forms. We h ave deviseda special connection for holding the forms in spaced relation, said connection being used -in conjunction with movable locking or wedging devices carriedby. the form units.

Our invention furthermore involves a novel type of metal form unit clamp for connecting units together.

Our invention additionally involves a special cooperative construction of tie rod connector `between spaced units, locking means therefor, and clamping means f or connecting sections or units, together 4with other detailed features of construction that will appear more fully as this description proceeds.

In the accompanying-drawings: j

ments and constructions illustrated inthe other ligures of the drawing. Figure 5 is an enlarged detail view bringing out the coaction between the locking member or wedge and the clamp.

Figure 6 is a sectional view taken about on the line 6-6 of Figure 5. i

We have illustrated in our drawings metal forms of a type known on the market today as metaforms, These forms consist of metal plates l equipped at their edges with angle plates or bars 2 and assembled by being placed together edge to edge, so to Speak, `or angle bar edges flat against one another. The angle bars 2 form flanges 4 at the edges of each of the'wall form units or sections which are as a whole designated as If desired, the plates l of yeach form nuit may be reinforced by intermediate angle bars or plates 3. This latter is immaterial to the invention.

Referring to Figure 2 it will be observed that two sections or units of metaforms are set up in vertical positions spaced apart.

'A number ofV these sections in horizontal arrangement will be held aligned by horizontal aligners B having suitable means C to connect them with the forms or units, these features not having to do particularly with our present invention.

To connect the spaced forms or units A together in substitution for the tie wires ordinarilyemployed, we untilize tie rods 5. These rods pass through openings at the edge portions of the forms .and through openings in the angle plates 2 located at such portions.

As it is desirable to positively prevent separating movement of the forms A when properly spaced we provide in the flanges i of adjacent units vertical or otherslots through which pass the locking members in the form of wedges 6. The wedges 6 are adapted to engage either one of two tie rods 5 that pass transversely through the form units, and thus lock the latter positively in proper relative positions. For facilitating the operation of one wedge 6 with two adjacent parallel tie rods 5 as seen inFigure l, the tie rods may be arrangedto pass through openings in slightly different horizontal planes, so that the wedging edge of the member 6 may have effective coaction with the two rods.

We have designed a special form of clamp for our forms. This clamp is seen best in Figures 5 and 6 and is designed to engage adjacent abutting flanges of two adjacent forms, as seen in Figure 4, to lock the forms together. Clamps like those of our inven tion as heretofore used have been riveted to the flanges 4 of the forms and supported wholly by said flanges. The tendency of a clamp so fastened is at times to pull the rivet through the angle plate 2 if any unusual strain 'is placed upon the said part.

To avoid the foregoing objection we have applied to the form section a casting or bracket 7 to form a bearing or support for the rivet 8 which pivotally connects one jaw 9 of the clamp l0 to the angle plate 2. By using the bracket 7 which is itself riveted to the form unit on top of the angle plate 2, we obtain a bearing for the rivet 8 at both of its ends, and this strengthens the connection of the rivet to the form or unit in a very satisfactory way in practice. The jaw l1 of the clamp l() is spaced from the jaw 9 and the manner in `which the two jaws engage the flanges 4 of the forms or units is quite evident on reference to Figure 6. IVe note, however, that the jaw 9 1s formed with a downwardly extending projection 9 that is aperturedfor the reception of the rivet 8 by which the clamp is pivoted upon the parts by which it is supported.

In conjunction with the tie rod feature of our invention'we indit useful to create an interlock between the clamp l0 andthe wedge or locking member 6 and this is done by so arranging the said parts that the locking member when engaged with one or more of the rods 5 is adapted to correspondingly engage the upper portions of the jaws 9 and l1 of the clamp l0, as seen in Figure 5. Thus accidental disengagement of the clamp 10 from the angle plate flanges 4 is absolutely prevented, and if desired the clamp 10 may have slight shoulders 1l and 9 on the jaws 11 and 9 respectively to positively abut with aside of the locking member 6 when the parts 6 and' l0 are in cooperation.

It will, of course, be evident that the shoulders 9 and l1 are not needed for the purposes of the invention. Te comment also upon the fact that to subserve the rigidity of the connection between the various parts as described we preferably employ a bracket 12 somewhat like the bracket 7, on the edges of the form units which lit against the edges which. carry one or more plates 7. The two brackets 7 and l2 afford very ample bearing for the wedges or locking members 6 that coact with the tie rods a considerable greater bearing than afforded solely by the slots in the flanges 4 through which the wedges 6 pass.

The employment by us of the rods 5 facilitates greatly the setting up of our form units in getting ready for work as much time is saved over the practice of using the tie wire connections.. Also the units may be more accurately positioned respecting one another than is obtainable by the old method. In practice we have found our whole system of tie rod connections and clamp or locking member cooperation, extremely effective in use to provide a rigid setting up of the metal forms, and obviate possibility of displacement or breaking off of the clamping means intermediate the units.

Having thus describedv our invention what we claim as new and desire to secure by Letters Patent, is:

l. In combination, spaced form units, tie rods extending across the space between the units and having their opposite ends passing through the latter, angle plates on the form units adjacent to the ends of the rods, and wedges slidable at right angles to the tie rods and engageable with the latter 4to lock them connected with the form units, and clamps connecting the form units together and cooperating with said wedges.

2. In combination, a form unit comprising a platek having an edge flange, a'jaw clamp pivoted to said plate and having its jaws adapted to embrace the edge lianges of two adjacent units for clamping kthe same together, a tie rod passing through the form unit at substantially right angles thereto, and a locking member intermediate said rod and the clamp and movable to engage the rod to lock the same in relation to the unit.

In combination, spaced form units, a tie rod extending transversely therethrough and across the space therebetween, and locking members for holding the tie rod positively against movement relatively to the formunits, and separate clamps yfor securing the form units together Fadapted to be engaged by the locking members ofthe tie rods and prevented from movement by such cooperation.

4. In combination, spaced form units, tie rods extending across the space between the units and having their opposite ends passing through the latter, angle plates on the form units adjacent to the ends of the rods, and wedges slidable through said angle' lplates at right angles to the tie rods and engageable with the latter to lock them connected withthe form units, and clamps connecting the form units together and cooperating with said wedges, and said clamping members comprising jaws to embrace and clamp together the angle plates attached to the form units, thus clamping the form units in operative connection.

5. In combination, a form unit provided with an edge flange, a bracket applied to said -lange and spaced therefrom, a clamp pivoted to said form unit and having flange embracing jaws, and a pivot connecting the clamp to the form unit and supported by said flange and said bracket.

6. In combination, a form unit provided with an edge flange, a bracket applied to said unit and spaced from the flange, a clamp pivoted to said form unit and having flange embracing jaws, and a lever for connecting one of the jaws of the clamp to the form unit and mounted with its ends supported by the angle plate and said bracket, substantially as set forth.

7 In combination, a form unit comprising a plate having an edge flange, a jaw clamp pivoted to said plate andhaving jaws to embrace the edge flanges of adjacent plates whereby to connect the plates together, and

a locking member to engage said clamp Iand interlocked with the unit so as to prevent unauthorized movement of the clamp.

8. In combination, a form unit comprising a plate having an edge flange, a jaw clamp pivoted to said plate and having jaws to embrace the edge flanges of adjacent plates whereby to connect the platees together, and a locking member to engage said clamp and mounted so as to prevent unauthorized movement of the clamp, and a tie rod passing through the plate of the form unit and adapted to be engaged by said locking member.

In testimony whereof we aflix our signatures.
